Application flled'December 13. 1921. Serial No. 522,040.

To all whom it may concern:

Be it known that I, OSCAR T. ANDERSON,

a citizen of the United States and a resident of Matel'loo, County,

useful Improvements in Wringers,

of America, Blackhawk Iowa, have invented certain new and of which the followmg is a specification.

y wringers, and ments are these; first, to so ing-seats of the upright invention relates to improvements in the objects of my improvedesign thebearparts of the frame and the roller bearing-boxes therein that the latter may be said bearing-seats removed upwardly from without difficulty, and second, to so construct the upper closure of the frame above the rollers of late ing parts to permit of such e of the bearing-seats, and to rally swingasy removal supply said laterally moving parts with roller-spring tensioning means and also with easily manually actuable releasable interlocking connections which may serve as saf quickly relieving the spring uppermost roll in case of ety means in tension on the necess1ty WhllG separating said interlocking connections.

These objects I have accomplished by the means which are hereinafter described and claimed, and which are illustrat companying drawings,

2 are like side elevations of my the laterally wringer showing respectively swinging top closure parts in and in their opened positions.

ed in the acin which Figs. 1 and improved their closed Fig. 3 is a top plan of the wringer as shown in said Fig. 2. Fig. 4 is a top plan wringer with said top closure and secured together, and Fig.

view of the parts closed 5 is an end elevation of the wringer with said top closure parts closed. Fig. 6 is a side elevation of the wringer showing the top closure apart to open positions, roller bearing seats lifted and tirely clear of the wringer fr parts swung and showing the removed ename.

Similar numerals of reference denote corresponding parts throughout views.

the several My improved wringer may be made of any suitable material or of different dimensions and with various modifications in its parts and their relatlve arrangements,

without de arting from the invention.

erein, I have shown a preferred illustrated construction wherein the frame and other parts, except the coacting resi lient rubber rollers 20 ,and 21, are all of metal, mostly of steel.

The rigid U-shaped main frame comprises like outwardly channeled uprights 1 fixedly mounted on the extremities of a horizontal tubular beam 2. These uprights are connected midway of their heights on opposite sides by horizontal brace-bars 3. The upper parts of top longitudinal openings with outwardly directed and. oblique side flanges 23, and like inwardly flanged pieces 22 are welded or othewise secured on the inner faces of the uprights and together with the flanged parts 23, serve as vertical slid'eways to receive the anti-frictional bearing boxes 24 and 25 of the shafts or spindles of said rubber rollers 20 and 21. A bifurcated. flanged plate 18 is secured to each box 24 and its lower forked part is positioned astride the shaft of the lower roller 21 and serves as a closure or guard adjacent the inner faces of'said uprights. A rectangular plate 19 extends upwardly from each .box 24 and has a horizontal slot to removably receive an end of an upwardly bowed plate-spring 16. 17 is a housing plate coverin the upper part of the hollow between the anges of the uprights 1 and'upon these plates 17 like closurebars 4 and 5 are with their downward extensions 6 swingingly pivoted at 7 to swing to and from each other laterally.

Each closure-bar or part 4 or 5 is bowed upwardly and she. ed with an angular cross sectionwhereby w en these parts are closed together they form a closed top open bottom housing for the midddle upper part of the spring 16. The numeral 9 denotes an arcuate bar having one end hinged at 8 medially to the outer face of the closure part 5 to swing to and from across it and over and fitting both parts 4 and 5 when the latter are closed together as shown in Fig. 5. A medial opening in the bar 9 is interiorly threaded to receive a tensioning screw 10 whose lower part traverses registering semi-circular notches below in said parts 4 and 5, so that the screw may be manually used to engage the spring 16 thereunder and place it under tension to thus yieldingly force the uppermost roller 20 toward the lower roller 21. Hin ing at 8 of the curved bar 9 insures uic engagement or disengagement with t e closure parts 4 and 5 without interferthe webs of the uprights 1 have open once, as in certain emergencies it may be important that the parts 4 and 5 may be instantly thrownapart.

An open top boxing 11 on the closure part 4 contains a cross pintle 15 on which is pivoted the lower end of a hand lever 12 having an angular catch 14 which, when the latter is swung upwardly, may releasably engage a fixed pin 13 on the hither side of the curved bar 9 to interlock the parts 4 and 5 together detachably. As the handle part of the lever 12 is terminally widened and shaped to overhang the part 4, it may be operated to disengage from the pin 13 by manual pressure downwardly.

' The compressed spring 16 immediately reacts upwardly sufiiciently to throw the parts 4: and 5 outwardly oppositely beyond their centers of gravity to become lowered to the positions shown in the lower part of Fig. 6. Even if the spring reaction is not enough to separate these parts to that extent, the upper rollcr is nevertheless relieved from tension instantly so that this improvement becomes an efiicacious safety device for the operator, 1n preventing 1nury to the person or garments when acci- -dently drawn between the rollers. As hereters Patent, is:

1. The combination with spaced frameuprights of a wringer, of parts hinged to the uprights to swing to and from each other laterally, coa'ctin rollers, resilient means bearing upon sai rollers, adjustable means mounted on one of said parts to releasably tension said resilient means, and means for releasably locking said parts when closed together.

2. In combination, a wringer havin rigidly connected spaced upri hts provid with open top seats, upwa y-removable hearings in said seats, and resilient means removably mounted upon said bearings, a pair of elementshaving their end parts hingedly connected to opposite parts of the tops of said uprights to swing to and from each other laterally, adjustable tensionproducing means mounted on one of said elements to tension said resilient means when the elements are closed together, and means for releasably locking said elements together. v

3. In a wringer, a frame having rigidly basally connected uprights, said uprights having bearing-recesses open at the to journal-boxes mounted in and upwar y removable from said recesses, coacting rollers mounted rotatably in said boxes, topclosing means comprising a pairof elements hinged to said uprights to swing to and from each other laterally, resilient means mounted to bear upon the u permost roller yieldingly, means mounte adjuston one of said elements to compress resilient means, and releasable locking connections between said elements including a releasing-member operable manually to disconnect said elements to allow the resilient means to reactively throw apart said elements and relieve the tension of said resilient means upon said uppermost roller.

Signed at Waterloo, Iowa, this 3d day of Dec. 1921.
